You just have to fudge it in there, all of or DPs are different. Get a 2.25" or 2.5" mandrel donut and go to town, the first foot or so is a pain in the ass.

^^^ Word to that. The dezod DP that is advertised as AC compliant with his kit, is not AC compliant with every other snail out there. I found that out the hard way. Just make sure that when you wrap the donut back under the snail you leave room to get the bolt in as well.
